I asked a defensive coach who was on a state championship high school team in my state about the 3-4 defense. He said it require very smart players who could analyze situations and know their assignments given the designated linebacker that would blitz. He told me the 3-4 is better against the pass than the run. He preferred the 4-3 because it was more effective against the run. But what most struck me was his comments about the intelligence required to operate a 3-4 effectively. This goes in line with previous Saban comments. Big, smart guys across the board, but especially on defense. The big is probably due to the vulnerabilities of this defense against the run.
